Abstract (en)
A lubricating base oil composition improved in flash point and low temperature fluidity without decreasing the high temperature traction coefficient, and a process for producing the same are provided. The lubricating base oil composition comprises (a) from 80 to 98% by weight of a naphthenic synthetic lubricating base oil having a flash point of 180 DEG C or less, and (b) from 2 to 20% by weight of a paraffinic synthetic lubricating base oil having a flash point higher than that of the naphthenic synthetic lubricating base oil.
